【摘要】 将两个具有合适能带结构的一维三元光子晶体组成光子晶体异质结,利用传输矩阵法研究了该结构的光学传输特性.计算结果表明,利用该结构可以有效地扩大全方向反射的频率范围,并且减小了在实际制作过程中随机误差引起的无序对光子带隙的影响.这种异质结构的多元光子晶体可用于制作全角宽带反射镜等光学器件.更多还原

【Abstract】 We show theoretically that the omnidirectional total reflection frequency range of a multilayer dielectric reflector can be substantially enlarged by using photonic heterostructure. This photonic heterostructure consists of two one-dimensional polybasic photonic crystals composed of three kinds of dielectric mediums with proper photonic band structures. The photonic band structures and transmission spectra were studied by the transmission matrix method and influence of the disorder is considered.更多还原
